feat(backend): Implement Phase 2.7 Task 1 - Medication Management System
This commit implements the complete medication management system, which is a critical MVP feature for Normogen. Features Implemented: - 7 fully functional API endpoints for medication CRUD operations - Dose logging system (taken/skipped/missed) - Real-time adherence calculation with configurable periods - Multi-person support for families managing medications together - Comprehensive security (JWT authentication, ownership verification) - Audit logging for all operations API Endpoints: - POST /api/medications - Create medication - GET /api/medications - List medications (by profile) - GET /api/medications/:id - Get medication details - PUT /api/medications/:id - Update medication - DELETE /api/medications/:id - Delete medication - POST /api/medications/:id/log - Log dose - GET /api/medications/:id/adherence - Calculate adherence Security: - JWT authentication required for all endpoints - User ownership verification on every request - Profile ownership validation - Audit logging for all CRUD operations Multi-Person Support: - Parents can manage children's medications - Caregivers can track family members' meds - Profile-based data isolation - Family-focused workflow Adherence Tracking: - Real-time calculation: (taken / total) × 100 - Configurable time periods (default: 30 days) - Tracks taken, missed, and skipped doses - Actionable health insights Files Modified: - backend/src/handlers/medications.rs - New handler with 7 endpoints - backend/src/handlers/mod.rs - Added medications module - backend/src/models/medication.rs - Enhanced with repository pattern - backend/src/main.rs - Added 7 new routes Phase: 2.7 - Task 1 (Medication Management) Status: Complete and production-ready Lines of Code: ~550 lines

# 🐳 Docker Deployment Analysis & Improvements
|
||||
|
||||
## Current Issues Found
|
||||
|
||||
### 🔴 Critical Issues
|
||||
|
||||
1. **Binary Path Problem**
|
||||
- Dockerfile CMD: `CMD ["./normogen-backend"]`
|
||||
- But WORKDIR is `/app`
|
||||
- Binary should be at `/app/normogen-backend`
|
||||
- This causes "executable not found" errors
|
||||
|
||||
2. **No Health Checks**
|
||||
- No HEALTHCHECK directive in Dockerfile
|
||||
- docker-compose has no healthcheck for backend
|
||||
- Failing containers aren't detected automatically
|
||||
|
||||
3. **Missing Startup Dependencies**
|
||||
- Backend starts immediately
|
||||
- Doesn't wait for MongoDB to be ready
|
||||
- Causes connection failures on startup
|
||||
|
||||
4. **No Resource Limits**
|
||||
- Containers can use unlimited CPU/memory
|
||||
- Risk of resource exhaustion
|
||||
- No protection against runaway processes
|
||||
|
||||
5. **Running as Root**
|
||||
- Container runs as root user
|
||||
- Security vulnerability
|
||||
- Not production-ready
|
||||
|
||||
### 🟡 Medium Issues
|
||||
|
||||
6. **Poor Layer Caching**
|
||||
- Copies all source code before building
|
||||
- Every change forces full rebuild
|
||||
- Slow build times
|
||||
|
||||
7. **Missing Runtime Dependencies**
|
||||
- May be missing ca-certificates
|
||||
- SSL libraries might be incomplete
|
||||
|
||||
8. **No Signal Handling**
|
||||
- Doesn't handle SIGTERM properly
|
||||
- Risk of data corruption on shutdown
|
||||
|
||||
9. **Port Conflicts**
|
||||
- Port 8000 conflicts with Portainer on Solaria
|
||||
- Changed to 8001 (good!)
|
||||
|
||||
10. **Duplicate Service Definitions**
|
||||
- docker-compose.yml has duplicate service definitions
|
||||
- Confusing and error-prone
|
||||

|
||||
### Dockerfile Comparison
|
||||
|
||||
**BEFORE:**
|
||||
```dockerfile
|
||||
FROM rust:1.93-slim AS builder
|
||||
WORKDIR /app
|
||||
COPY . .
|
||||
RUN cargo build --release
|
||||
|
||||
FROM debian:bookworm-slim
|
||||
WORKDIR /app
|
||||
COPY --from=builder /app/target/release/normogen-backend .
|
||||
CMD ["./normogen-backend"] # ❌ Wrong path
|
||||
# No health check, runs as root
|
||||
```
|
||||
|
||||
**AFTER:**
|
||||
```dockerfile
|
||||
# Build stage
|
||||
FROM rust:1.93-slim AS builder
|
||||
WORKDIR /app
|
||||
COPY Cargo.toml Cargo.lock ./
|
||||
RUN mkdir src && echo "fn main() {}" > src/main.rs \
|
||||
&& cargo build --release && rm -rf src
|
||||
COPY src ./src
|
||||
RUN cargo build --release
|
||||
|
||||
# Runtime stage
|
||||
FROM debian:bookworm-slim
|
||||
RUN useradd -m -u 1000 normogen
|
||||
WORKDIR /app
|
||||
COPY --from=builder /app/target/release/normogen-backend /app/normogen-backend
|
||||
USER normogen
|
||||
EXPOSE 8000
|
||||

|
||||
CMD curl -f http://localhost:8000/health || exit 1
|
||||
ENTRYPOINT ["/app/normogen-backend"]
|
||||
```
|
||||
|
||||
### docker-compose Improvements
|
||||
|
||||
**BEFORE:**
|
||||
```yaml
|
||||
services:
|
||||
backend:
|
||||
image: normogen-backend:runtime
|
||||
ports:
|
||||
- "8001:8000"
|
||||
environment:
|
||||
JWT_SECRET: example_key_not_for_production
|
||||
depends_on:
|
||||
- mongodb # No health check!
|
||||
```
|
||||
|
||||
**AFTER:**
|
||||
```yaml
|
||||
services:
|
||||
backend:
|
||||
build:
|
||||
dockerfile: docker/Dockerfile.improved
|
||||
environment:
|
||||
JWT_SECRET: ${JWT_SECRET} # From env var
|
||||
depends_on:
|
||||
mongodb:
|
||||
condition: service_healthy # ✅ Waits for healthy
|
||||
healthcheck:
|
||||
test: ["CMD", "curl", "-f", "http://localhost:8000/health"]
|
||||
interval: 30s
|
||||
timeout: 10s
|
||||
retries: 3
|
||||
deploy:
|
||||
resources:
|
||||
limits:
|
||||
cpus: '1.0'
|
||||
memory: 512M
|
||||
```
|

|
||||
|
||||
## Deployment Steps
|
||||
|
||||
### Option 1: Automated (Recommended)
|
||||
|
||||
```bash
|
||||
# 1. Set environment variable
|
||||
export JWT_SECRET="your-super-secret-key-at-least-32-characters"
|
||||
|
||||
# 2. Run improved deployment script
|
||||
./backend/deploy-to-solaria-improved.sh
|
||||
```
|
||||
|
||||
### Option 2: Manual
|
||||
|
||||
```bash
|
||||
# 1. Build locally (faster than building on server)
|
||||
cargo build --release
|
||||
|
||||
# 2. Create directory on Solaria
|
||||
ssh solaria 'mkdir -p /srv/normogen/docker'
|
||||
|
||||
# 3. Create .env file on Solaria
|
||||
ssh solaria 'cat > /srv/normogen/.env << EOF
|
||||
MONGODB_DATABASE=normogen
|
||||
JWT_SECRET=your-secret-key-here
|
||||
RUST_LOG=info
|
||||
SERVER_PORT=8000
|
||||
SERVER_HOST=0.0.0.0
|
||||
EOF'
|
||||
|
||||
# 4. Copy improved Docker files
|
||||
scp docker/Dockerfile.improved solaria:/srv/normogen/docker/
|
||||
scp docker/docker-compose.improved.yml solaria:/srv/normogen/docker/
|
||||
|
||||
# 5. Stop old containers
|
||||
ssh solaria 'cd /srv/normogen && docker compose down 2>/dev/null || true'
|
||||
|
||||
# 6. Start with new configuration
|
||||
ssh solaria 'cd /srv/normogen && docker compose -f docker/docker-compose.improved.yml up -d'
|
||||
|
||||
# 7. Check status
|
||||
ssh solaria 'docker compose -f /srv/normogen/docker/docker-compose.improved.yml ps'
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Verification
|
||||
|
||||
```bash
|
||||
# Check container status
|
||||
ssh solaria 'docker ps | grep normogen'
|
||||
|
||||
# Check health status
|
||||
ssh solaria 'docker inspect --format="{{.State.Health.Status}}" normogen-backend'
|
||||
|
||||
# View logs
|
||||
ssh solaria 'docker logs -f normogen-backend'
|
||||
|
||||
# Test API
|
||||
curl http://solaria.solivarez.com.ar:8001/health
|
||||
```
|
||||
